The SitePoint PHP blog has another post in its series about working with Drupal 8. In this new tutorial author Daniel Sipos talks about theming views in the content management system and introducing custom style plugins.

In this article, we are going to look at how we can create a custom Style plugin for Views in Drupal 8. We will use the Bootstrap tab markup as a goal and implement a tabbed output for our View results. In the View configuration, the Style settings will allow us to specify which field will be used as the tab navigation copy, leaving the rest of the fields shown in the respective tab panes. Basically, each View result will represent a tab – so this example is not suited for Views which have more than a few results. The main goal is to illustrate how we can create our own Views Style plugins in Drupal 8.

He starts by talking about Style plugins - what they are and where they fit in the application execution flow. He then walks you through the creation of the custom style plugin to integrate the Bootstrap tabs. This also includes the creation of the theme and the matching template to build out the tab markup.
